Small molecule OLED's based on the phosphorescence emission of Os, Ru, Re, Ir, and Pt based complexes have received a great deal of attention to date. Phosphorescent chromophores have the potential for much higher electroluminescent quatum efficiencies because they can emit photons through multiple pathways. The theoretical internal quantum efficiency of a triplet state emitter approaches 100% because both excitons from the triplet and singlet states produce light emission. Of these types of metal complexes phosphorescent Iridium [III] complexes are of great interest because they can exhibit external quantum efficiencies of up to 20%. In addition, their emission wavelengths can be tuned throughout the entire visible spectrum by varying the ligand structure. However, there is a need for a better host material for Ir [III] compounds to help improve device properties and fabrication. This project is focused on using PFCB polymers as a host material for Ir [III] complexes through both blending and copolymerization.
